Can anyone tell me what these little red tube things might be?

spionid worms.

Good or bad? Never seen the red ones before.

They are filter feeders and harmless. I notice they annoy some of my corals but not enough to do any damage.

You can glue them shut if u see them really annoying corals..

What the OP is asking about are vermited snails.

They are harmless, though can be annoying to look at as they throw out a 'web' to catch particles in the water column, and then reel it back in to eat.
Excess amounts of these guys usually mean there is too much particulate type food in the tank.
